My Most Used AWS Services and What I Use Them For

If someone asked me to list the AWS services I use most often, I would not list them in order of hype. I would list them in order of usefulness.

These are the services that show up repeatedly in my work because they solve common problems without creating unnecessary complexity.

Lambda

I use Lambda for lightweight background processing and event-driven tasks. It is useful when I want to avoid managing servers for small pieces of logic.

This is especially helpful for webhooks, scheduled jobs, media processing, and small integrations.

S3

S3 is my default for storing files and static assets. It is simple, durable, and easy to integrate with other AWS services.

I use it for uploaded content, backups, logs, and static site hosting when the project fits that model.

IAM

IAM is not exciting, but it is essential. I use it to manage access tightly and keep services separated by role.

The more a system grows, the more important this becomes.

CloudWatch

CloudWatch is where I look when I need visibility. Logs, metrics, alarms, and dashboards all matter when the system is running in production.

It is one of the services that saves the most time during incidents.

RDS

RDS is my default for relational data when I want a managed database without the overhead of operating one myself.

It gives me a strong balance of reliability, tooling, and simplicity.

Route 53 and CloudFront

For public-facing systems, these are often the right combination for domain routing and content delivery. CloudFront helps performance, and Route 53 helps with DNS and routing decisions.

The pattern behind the list

The services I use the most are usually the ones that help me move quickly while keeping the system safe and observable. That is the real barometer for me.

If a service makes the system easier to operate and easier to understand, it earns a place in my stack.
